Google Gemini API

Google's frontier model with the largest context window

8.7 / 10 26 Verified Reviewers Verified 2026-04-30 TypeScriptPythonGoJava

Gemini 2.5 Pro and Flash deliver competitive frontier-class quality with the longest production context window (2M tokens on Pro). Native multimodal handling (video, audio, images, code) is unmatched. The catch: API stability has been uneven through 2025-2026, and the SDKs have shifted twice. Best fit when context length or multimodal genuinely matters.

Pricing
From $1.25/M input, $5/M output (Gemini 2.5 Pro)

2M context is the only reason we picked it.

We process hour-long video transcripts plus context. No other provider can do this in one call without chunking. Gemini's native multimodal is genuinely a moat.

Quality is fine. Stability is not.

API rewrites broke our prod twice in 2025. Quality benchmarks favor Gemini for some tasks but the operational tax is real. Watching closely for 2026 stabilization.

The Vertex AI integration is the unfair advantage.

We're GCP-native. Gemini through Vertex auth gives us IAM, audit logs, regional pinning out of the box. That's worth more than a 10% quality differential.
